Wow! This is a gadget: Ferrofluid from 11,81€

I’ve stumbled across the video on the web once again with the magnetic ferrofluid, and I’m backed up by the idea. Have me a bottle now simply times ordered and at the occasion the prices here in the article adjusted. At Banggood there is the “magic” liquid in the bottle for 11.81 € when you enter our voucher pandacheck.

Ferrofluid was developed years ago by NASA to investigate the behavior of liquids in gravity in space. Meanwhile, the liquid is also used in high-end loudspeakers: for cooling or damping. Ferrofluid consists of a carrier liquid (here oil) and tiny, tiny small magnetic elements. These are so small that they can not be seen with the naked eye (5-10 nanometers) and thus do not settle with the time.

Ferrofluid consists of tiny magnets and carrier liquid

Since there are quite a few Neocube spheres, or other magnets at home, this liquid is perfectly suited for creativity and experimentation. There are, of course, also hobbyists, who try to recreate such mixtures – but it seems to really work behind it. So you have either a new chemistry hobby or a gadget hobby – just think of macro recordings! In addition, you can do a lot with the magnetic fluid – for example, you can build a 7000 Euro watch:

I just mention it once again: No, you really should not drink the stuff, no, it is not suitable for younger children, yes it makes on the clothing spots and yes the “black spiderman” was inspired by the ferrofluid ;-). In addition, of course, magnetic materials should not be nearby ;-). In the comments there are already nice ideas – only your photos are still missing!
